Answer:

40 $1 bills. 30 $5 bills. 15 $10 bills. 4 $20 bills.

Step-by-step explanation:

In order to find how many there are of each in total, use the multiplication, division, subtraction, and addition property of equality.

For example, take the first equation. 1/2x +7=27

Follow these steps using the equalities

1/2x+7-7=27-7 Subtraction property of equality

1/2x·2=20·2 Multiplication property of equality

x=40

Do the other properties to find all the other equations. Here's the steps you should follow

5=1x-25

5+25=1x-25+25 Addition property of equality

5=x

3x+9=54

3x+9-9=54-9 Subtraction property of equality

3x/3=45/3 Division Property of equality

x=15

16=5x-4

16+4=5x-4+4 Addition Property of Equality

20/5=5x/5 Division Property of Equality

4=x

Hope this helped
